Advise please!!

ja

I'm 24years old and have been ttc for 8 months now my partner is 15yrs older than myself and we are desperate to start our own family we are following all the advise the internet is saying when ttc like cutting out alcohol not having coffee anymore exercising more. We also take pregnecare tablets which are full of vitamins and I take folic acid. Im trying to track when I ovulate with the sticks but 8 months on and still nothing and it breaks our hearts every month when my period appears. I have never been pregnant before and my partner has never had a child before. Is it to early to start worrying that it might not happen for us. Advise would be great.
